Well, it's full of holes and preposterous situations, it's got lots of bad dialogue and you can predict pretty much the entire story within the first 15 minutes... but man, I still had fun. Brainless fun, obviously, that relied entirely on the frenetic action sequences and entertaining banter between the two main characters (mostly Travolta's lines), but fun nonetheless.
However, it isn't even close to being as good as Taken; despite sharing many of the same flaws, none of Taken's positives are here, except for some well-shot action. Also, when I mentioned holes, I meant it: I don't think there's a single situation or plot point that didn't make me think "wait, what?". Seriously, it's ridiculous. But also badass, in a cliché kind of way.
In a sentence:
Not an ounce of originality, unpredictability or sense is present here, but it's full of frenetic action and brainless fun.
